This also applies in the PCT. The Official PCT Request form contains a box where, if relevant, the applicant may indicate how he acquired the right to claim priority (e.g. by transfer, assignment, agreement, change of name).

The Patent Cooperation Treaty ( PCT ) system allows for the preserving of foreign patent rights if the PCT application is filed within twelve (12) months of the priority date of the parent application. Preserving priority is of the utmost importance, but what if a priority claim made in the PCT Request was incorrect or incomplete? The right to claim priority The right to claim priority is established by the Paris Convention, which states that any person who has filed a patent application, or his successor in title, shall enjoy a right of priority.

The relevant provisions of the PCT , EPC, and UK Patents Act are based on this 4. Obligation to Submit Copy of Earlier National or International Application. Rule 17The Priority Document.

Careful reading of this rule reveals that the members of the WTO in which priority applications recognised under this rule may be filed need not be states as such. However, in situations where this backdoor route is available for timely submitting the PCT patent application before a previously closed receiving office, it may provide an effective resolution for retaining an otherwise lost priority claim back to the original first patent application, and in a way that obviates the need to undergo the onerous restoration process. Deficiencies in the priority claim and loss of the priority right Four potential deficiencies exist with regard to the priority claim , namely: Art.
